MobileSIM eSIM Data Plans for East Asia

MobileSIM does not provide an unlimited‑data eSIM for East Asia.
Instead it offers a selection of fixed‑data plans, such as the Asia 100 GB for 180 days plan that delivers 100 GB over six months for $185.00 USD, or the Asia 50 GB for 90 days plan that supplies 50 GB for three months at $100.00 USD. These plans cover China, Hong Kong, Japan, Macau, South Korea, Taiwan and 12 other countries. Choosing a fixed‑data plan can be more cost‑effective for most travelers, unless a user is an extremely heavy data consumer.

MobileSIM does not provide East Asia eSIM plans that include a local phone number or SMS capability. Only data‑only eSIMs are available in this region. Travelers can still make and receive calls and send messages using internet‑based applications such as WhatsApp, Telegram, or iMessage, which operate over the data connection and do not require a traditional phone number.

MobileSIM’s East‑Asian coverage is provided through two eSIM plans. The “Asia for” plan serves China, Hong Kong, Japan, Macau, South Korea and Taiwan, while the “Global for” plan covers the same six East‑Asian countries plus Mongolia and extends its reach to a broad set of additional regions outside East Asia. All countries listed above are the ones available in the approved East‑Asian group of Japan, Hong Kong, China, South Korea, Taiwan, Macau and Mongolia.
